RICHARD WILLIAM DERBYSHIRE', OF DAGENHAM, ENGLAND.

TIDAL MOTOR.

sraorrroncrron forming part of Letters Patent No. 700,408, dated May 20,1902. Application filed March 10, 1902. Serial No 97,466- (No model.)

To all whom it may concern.-

Be it known that I, RICHARD WILLIAM DER- BYSHIRE, engineer, a subject ofthe King of GreatB ritain and Ireland,and a resident of the Cross Keys,Dagenham, in the county of Es has been filed but-not yet sealed,) ofwhich the following is a specification.

My invention relates to the utilization of a tidal rise or fall and thecurrent of water-flow incidental thereto for operating a dynamo-.

' electrical lamps, and for like purposes.

In order that my invention may be clearly understood, I have appendedthe accompanying sheet of drawings, in which- V Figure 1 is a sectionalelevation of the gen-, eral device. Fig. 2 is an end elevation thereof,also sectional. Fig. 3 is an elevation of part of the outer ring,showing the means adopted for varying the angle of the buckets. Fig. 4is anend sectional elevation thereof; and Fig. 5 is a view of. the outerring, showing the screwed lug in place within the slot.

Similar letters of reference indicate corresponding parts throughout theseveral views.

In carrying my invention into effect I employ a moored raftor barge witheither swimheaded or tapered ends, which is placed in' a tideway and hasa central channel B, suitably shaped to provide for the rotation of theundershot O by the Water-current set up by the tide. The buckets b maybe set to any angle within their range by a slotted ring D on one sideand a guide-ringD on the other side, these rings being joined bycross-bars E, passing from-D to D under the periphery F of the wheel 0and between the arms thereof, so that both rings may movesimultaneously. annular flange F on the inner side of the periphery F ofwheelC, and so maintain the rings D D in a concentric position on thewheel 0. Each bucket b is freely bedded in the periphery F, between apair of angle-strips F on said periphery, and attached by free pivots orpins 0 to the rings D D,

. gates temporarily during adjustment.

The cross-bars E slidably bear on the which form the sides of the wheel.'A head H, similar tothe puppet-head of a lathe, is attached to D andhasa screw J, which engages with -a screwed hole in the lug K, which isattached to and projects from the periphery F, upon which the buckets bare freely swung. A hand-wheel I controls the screw J, and when it isdesired to reverse the angle of the buckets b or to regulate said anglethe hand-wheel I is turned in either direction, so as to move theslotted ring D and the opposite ring D relatively to the periphery F.Said regulation or reversal is effected by stopping the wheel 0 by asluice gate or Since the apparatus is carried upon a floating raft orsplit barge, the immersion is always equal.

I prefer to couple the wheel 0 thus driven directlyto one or moredynamo-electric generators MM and either ballast the barge orv currentderived directly.

I may use two, three, or more wheels C inthe parallel space between theflotation por tions'of the raft, barge, or the like and may grade themso that each may take up the Having now particularly described and as- Iraft with accumulators in circuit or use the certained the nature of mysaid invention and in what manner the same is to be performed, I declarethat what I claim is- 1. In a device of the character described, awheel, rings carried by the wheel and adjustable thereon, and bucketsmounted in the a wheel and rings.

2. In a device of the character described, a wheel,.a ring carried bythe Wheel andadjustable thereon,-and buckets pivoted in the ring andloosely seated on the wheel.

3. In a device of the character described, a wheel, rings adjustablethereon,buckets pivoted in the rings and angle-strips on the pe-. I

riphery of the wheel between which the ends of the buckets are looselyheld.

4.. In a. device of the character described, a wheel having a fiatperiphery with an annu- IOU lar flange on its inner side,- a ring oneach side of the periphery, cross-bars connecting the rings and slidablybearing on the flange, buckets pivoted to the rings and loosely seatedon the periphery of the wheel, and In Witness whereof I have hereuntoset my means for adjusting the rings on the Wheel. hand in presence oftwo witnesses.

5. In a tidal motor, a raft or divided barge, n y an undel'shot Wheelmounted thereon, bnck- MOHARD WILLIAM DLRMSHIRL' 5 ets carried by theWheel and means for silVitnesses:
